To all whom it may-concern:

Be it known that I, Gnonc GOLDBERG, of 329 Prinsengracht, Amsterdam, Netherlands, a subject of the Emperor of Germany, have invented a certain new and useful Improvement in Valves for Carbonated-Liquid Receptacles, of which the following is a full My said invention is fully shown and de scribed in the following specification of which the accompanying drawings form a part, wherein similar letters of reference designate like or equivalent parts wherever found throughout the several views, and in which Figure 1 is a view in central vertical section of a bottle top provided with my new and improved valve; Fig. 2 is a side view in detail of the valve, the coupling union of the service pipe through which. the receptacle is to be filled, being shown in ver tical section and looked upon the valve casing so as to open the valve. Fig. 3 shows the plug in the closed position, the coupling union being shown detached and in process of removal. Fig. 4: is a bottom view of the coupling union. Fig. 2 is a top view of the valve-casing and plug in the open position shown in Fig. 2, the lower portion thereof being a cross section taken on the line I-I of Fig. 2, while Fig. 8 is a like view showing the like parts in the closed position shown in Fig. 3, on line ITII. Fig. 5 is a side view of a key by which the valveplug may be turned so as to open or close the valve when it is desired to fill the same or dispense the liquid. Fig. 6 is a plan view of the two members of a split ring employed for holding the locking sleeve in place. Fig. 7 shows a side elevation of the same.

Referring to the drawing :-The reference letter 0; designates a bottle of any suitable form, and this bottle is provided at the ing down into the bottle mouth is the valve mouth with the enlarged head a. Extendcasing. Z) of the circular conical form shown,

provided near the lower end on one side with the tube orifice 7c, in communication with the tube m, which extends down into the bottle nearly to the bottom, and with a like orifice Z in free communication with the bottle at the upper end.

Fitting snugly in the valve-casing Z) is the valve turn-plug 0, which is provided with longitudinal passages 70 and Z,aclapted to be brought into and out of communication with the orifices 7c and Z by the turning of the plug. Such plug 0 is provided at the lower end with the screw threaded portion 9, having a nut 9 which is screwed tightly up so as to force the washer 9 against the lower end of the casing b. The valve casing b is provided adjacent to the top with the outwardly extending annular securing flange e which is of about the same diameter as is the head a of the bottle, between which and the bottle mouth, when in position thereon, is interposed the annular packing ring 7, of soft rubber or other suitable packing material. Passing down over the bottle head, is the securing sleeve (Z, provided at the bottom with a female screw thread as shown in Fig. 1, into which screws the male screw-thread of the split-securing ring z', which enables it to be placed in position upon the bottle neck beneath the head a. Such split-ring is split centrally on a line passing through its center into two semicircular parts; one member of thering having pins 2" and the other sockets i into which the pins fit as shown in Fig. 6, and between this split ring and the head a is usually interposed "a packing ring or washer it like the washer f usually of soft rubber, the valve casing being forced firmly into position on the bottle head a, by pressure upon the flange 6 by the inwardly extending flange cl of the securing sleeve d as shown in Fig. 1.

The valve-casing b is provided atthe upper end with a peripheral step flange 9, from the lower step of which extends outward securing pins 9, adapted to enter the bayonet joint slots t, of the securing cup at of the coupling union secured to the pipe 0, shown in Figs. 2 and 3; such union being provided is turned into the closed with the usual turning handles u. union coupling cup is provided with a passage 79 on either side of which within the cup, are the key pins r, adapted to enter the pin holes 8, in the upper part or face of the turn-plug 0, when the cup is placed on the valve, so that when turned so as to lock the cup thereon this will cause the turn-plug to be turned into the open position, and vice versa. The coupling cup is also usually provided with a packing washer or ring a, by which the joint between the same and the valve casing and plug is made tight when the parts are locked together.

My improved valve having first been secured in the bottle neck, the valve plug is turned into the open position by means of a thumb-key 25, having the pins 1", adapted to enter the holes 8 of such plug, and the bottle is then filled by way of the passage and pipe m, the air escaping by way of the orifices Z and passage Z. When sufficiently full, by means of the key 2,, the valve plug position shown in Figs. 3 and 3 and the bottle thus sealed is then subjected to a sufiiciently high temperature to thoroughly pasteurize the contents, this being done in any suitable apparatus, After pasteurizing the bottle is allowed to cool; then the coupling cup n of the union is locked thereon as shown in Figs. 1 and 2, which operation will again open the valve without bringing the contents into contact with the atmosphere; carbonic acid gas, under sufiicient pressure to properly impregnate the liquid in the bottle, is then led in through the pipe 0, and after sufficient interval the coupling is removed which will again hermetically close and seal the bottle by turning of the valve plug into the closed position, when the bottle and contents will be ready for shipment. hen it is desired to use the liquid, the coupling n bein of course withdrawn, it may be drawn 05 by turning the plug into the open position by means of the hand-key t, the liquid then passing out through the passages Z, Z. In pouring the liquid the bottle is tilted in the usual way.

It will be understood that the bottle is never completely filled with liquid which never reaches the valve mechanism. When the bottle stands upright there is always left over the liquid a space which receives carbonic acid gas. It will also be understood that after the bottle is filled with liquid it is hermetically closed. The liquid is then sterilized and after that it is cooled, inasmuch as this cooling promotes the absorption of the carbonic acid gas subsequently admitted. After the bottle is thus filled and the contents thereof sterilized, the bottle is coupled to the means for supplying carbonic acid gas in the manner before described, and

when the coupling is turned to a proper ex- This I tent, gas enters the bottle, air of course not being allowed to enter. Carbonic acid gas is absorbed by the liquid and this operation may be promoted by tilting the bottle, thus presenting a larger surface area for the absorption of the gas and this absorption may bestill further promoted by agitating or shaking the bottle during the introduction of the gas. After the liquid is charged with carbonic acid gas in the manner above described, the coupling a is withdrawn and the valve is closed.

What I claim is 1. The combination with a receptacle for liquid, of a valve casing having a port opening into the receptacle, means for securing the casing to the receptacle, a valve mounted to turn in said casing and having a passage extending from its outer end to the port in the casing, a coupling cup equipped with a tube and provided with means e11- gaging the valve for turning it within its casing and also with means engaging the valve casing for locking it thereto.

2. The combination with a receptacle for liquid, of a valve casing having a port opening into the receptacle, means for securing the casing to the receptacle, a valve mounted to turn in said casing and having a passage extending from its outer end to the port in the casing, a coupling cup equipped with a tube and provided with means engaging the valve for turning it within its casing, and a bayonet joint connection between the coupling cup and the valve casing.

3. The combination with a receptacle for liquid, of a valve casing having a port opening into the receptacle, means for securing the casing to the receptacle, a valve mounted to turn in said casing having a passage extending from its outer end to the port in the casing, and having sockets in its outer end, a coupling cup equipped with a tube and having lugs adapted to enter said sockets in the valve whereby the valve may be turned, and means for locking the coupling cup to the valve casing.

4E. The combination with a receptacle for liquid, of a valve casing having a port opening into the receptacle, means for securing the casing tothe receptacle, a valve mounted to turn in said casing and having a passage extending from its outer end to the port in the casing, lugs g projecting laterally from the valve, a coupling cup having slots adapted to engage the lugs and equipped with a tube, and means carried by the cup engaging the valve whereby the latter may be turned to open it in the act of locking the cup to the lugs on the valve casing.

5. The combination of a bottle having an enlargement at the outer end of its neck, avalve casing having a flange extending across the mouth of the bottle, a sleeve surrounding the end of the bottle neck and turning the valve and for locking the cup having a flange projecting over the flange to the valve casing. 10 of the valve easing, a two-part ring en- In Witness whereof I have hereunto set gaging the lower end of the sleeve and the my hand in presence of two Witnesses.
